arm: libgcc update to linux v2.6.37 ...

This patch removes the inclusion of libgcc functions into Barebox on the ARM
architecture. Only the really needed functions are provided in the lib_arm
directory. Those implementations are copied from Linux where they are well
proven related to reliably, performance.

Linking: Remove linker scripts from (arm based-) boards and add ...

a generic linker script to arch/arm/lib/u-boot.lds.S.
	 If a board wants to overwrite a linker script it can do
	 so using CONFIG_BOARD_LINKER_SCRIPT.
	 There is no generic linker script for ppc and blackfin
	 yet, so still use the board specific one.
